WILLIAM MANLEY, OF ROCHESTER, NEV YORK.

TRlMMlNG-CUTTER FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 342,371, dated May 25,1886.

Application filed August 5, 1885. Serial No. 173,505.

To all whom, it may concern.-

Be it known that I, WILLIAM MANLEY, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Boot and Shoe Trinr ming Cutters; and I do herebydeclare the following is a full and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification.

My invention relates to parts immediately connected with the feathenedgeor rand trimming knives employed on the cutter, whereby the said part ofthe sole edge is perfectly and rapidly trimmed at the same operation bywhich the main edge of the sole is trimmed, and whereby a perfectclearance of the cutter is obtained without any clogging thereof by thedust or shavings produced in the operation.

In the drawings, Figure 1 is a view of the outer end of a sole -edgetrimmer or cutter constructed according to my invention; Fig. 2, anaxial section of the cutter, of a portion of the spindle or shaft onwhich it is mounted, and of the guard and guide-disk employed inconnection therewith, the view taken in the line :0 :c, Fig. 1; Fig. 3,a side view of the cutter; Fig. 4, a view of the outer face of the guardand guide-disk used with the cutter; Fig. 5, a view of the inner side ofthe said disk.

Like letters designate corresponding parts in all of the figures.

The parts represented in the drawings are the cutter A, preferably madeof one solid piece and formed with peripheral sole edgetrimming knives ac, with spaces between them parallel with the axis of the cutter, andwith feather-edge-trimmingknives e 0, projecting from the peripheries ofthe other knives at their outer ends; the spindle B, on which the cutteris mounted; the guard and guide- (No model.)

feathenedge, welt, or rand trimming part of the cutter, and which are inpart coincident with the outer ends of the main edge-trimming knives,are made concave on the outer face of the cutter from the peripheriesthereof to the inner extremity or base thereof, as shown most clearly inFig. 2; or, if not entirely into the base of the cutters, at least farenough from the outer edges to furnish sufficient open spaces betweenthe cutters and the disk 0 to allow a free clearance of the dust andshavings produced by this part of the cutter. Vith this construction noholes or discharge openings are required through the disk C. To furtherprevent clogging and make the clearance more free, the rear edges, I) b,of this part of the cutter are rounded or beveled off, as shown mostclearly in Fig. 1; and this isall that is required in the constructionof the knives of the cutter to effect the purpose set forth.

Although the concave form of the ends of the cutter-knives is all thatis necessary to effect this purpose, I find that it is preferable tomake the interior surface of the shielddisk 0 also somewhat concaveopposite to these knives, as shown at f. This widens the spaces betweenthe knives and disk, and gives additional freedom to the passage of dustand shavings, and by it the concavity of the knives may be lessened, ifdesired.

Since the cutter knives e e are thin and slight, they are liable to beeasily damaged, and should not be subject to uneven pressure of the disk0 against them. I therefore provide for firmly securing the said disk toits spindle, so that it cannot swerve out of proper position. For thispurpose the screw D,which is screwed into the end of the spindle B, hastwo shoulders, g h, on the inner surface of the head, one bearing firmlyagainst the end of the spindle and the other bearing against the diskaround the eye through which the shaft of the screw passes, as shown inFig. 2. These shoulders may preferably be conical to fit incountersinks, thereby more perfectly centering the disk in position.

I claim as my invention- 1. The knives e 0, formed with concave ends androunded rear edges, I) b, substantially as and for the purpose hereinspecified.

2. The combination of the feather-edge or dered attaching-screw D,substantially as and rand trimming knives e 0, formed with 0011- for thepurpose herein specified. IO cave ends and rounded rear edges, 1) I),with Vitness my hand this 3d day of August, A.
